    <title language="eng">Hydrogen Solubility in Steels – What is the Role of Microstructure?</title>
    <abstract language="eng">Hydrogen gas plays a key role in the European energy transition strategy. When transmitting and storing compressed hydrogen gas, safety is one of the most important conditions. With increasing hydrogen pressure and temperature, more hydrogen is absorbed by the steel components, such as pipelines or valves, and may lead to embrittlement. Although, a deep understanding of microstructure on the hydrogen solubility in steels is missing. Classical Sieverts’ law is only valid at high temperatures and low gas pressures. For that purpose, new theory is presented, which explains the role of microstructure on hydrogen solubility. Hydrogen trapping at microstructural defects is a thermally activated mechanism and causes an increase of the hydrogen solubility with decreasing temperatures. This mechanism has to be considered in cryogenic applications, such liquid or compressed hydrogen storage.</abstract>
